Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do we call an electric charge that builds up on the surface of an object?
A
Ampere charge
B
Static charge
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit.

Detailed explanation-2: -Static electricity is the imbalance of electric charge on a surface of a material. Static means fixed or stationary, therefore it is used in contrast to dynamic (moving) electricity which are in the form of electric currents. Typically atoms are neutral, which means they have the same number of electrons and protons.

Detailed explanation-3: -It is called “static” because the displaced electrons tend to remain stationary after being moved from one insulating material to another.

Detailed explanation-4: -There are two main types of static electricity, volumetric and surface. Volumetric static charges are charge imbalances within the body of a material whereas surface static electricity is only present on the very outer surface of a material.
